You Focus on Their Progress. We’ll Focus on the Payors.

Mental health billing services carry documentation requirements, telehealth rule complexity, and prior authorization burdens that standard billing teams aren’t equipped to handle. One timed-code error or missing modifier costs you the entire session’s reimbursement.

Behavioural health billing is where the most revenue gets quietly abandoned.

Psychotherapy reimbursement depends on getting a narrow set of rules exactly right — the wrong time increment, the wrong place of service code, or a missing add-on modifier can deny or underpay a claim that represented 53 minutes of direct patient care. CPT code 90837 covers psychotherapy of 53 minutes or more; 90834 covers 38 to 52 minutes; 90832 covers 16 to 37 minutes. Each requires documentation of the total face-to-face time — and each is frequently billed at the wrong level because the timed documentation wasn’t confirmed before claim submission. Add tele-health complexity, prior authorization variability by payer, and the Mental Health Parity and Addiction Equity Act’s impact on benefit design, and behavioural health billing becomes one of the most policy-intensive revenue cycles in healthcare. Our full RCM services include behavioural health-specific workflows.

Timed Psychotherapy Code Accuracy

The distinction between 90832, 90834, and 90837 isn't just administrative — it's directly tied to the documentation in the session note. If a provider documents 50 minutes but charts a 90837, the claim is overcoded. If they see a patient for 60 minutes but bill a 90834, they're leaving revenue behind. Our coders verify time documentation against the submitted code on every claim, before submission.

E/M with Psychotherapy Add-On Codes

When a prescribing provider (psychiatrist or psychiatric NP) conducts both a medical evaluation and psychotherapy in the same session, the E/M service and psychotherapy are both billable — using add-on codes +90833 (16–37 min psych with E/M), +90836 (38–52 min), or +90838 (53+ min). This combination is one of the most underbilled services in psychiatry because providers either don't know the add-on structure exists or their billing team defaults to billing only the E/M. We capture it on every qualifying encounter.

Telehealth Place of Service and Modifier Rules

Telehealth billing in behavioral health requires specific place of service (POS) codes and modifiers that vary by payer and setting. POS 02 (telehealth — patient not in their home) and POS 10 (telehealth — patient in their home) are not interchangeable. Modifier 95 (synchronous telemedicine) is the standard for video visits; modifier GT is required by some payers. Audio-only visits require POS 02 with modifier 93 under Medicare. Applying the wrong combination results in automatic claim rejection — particularly common for practices that shifted to telehealth during the pandemic and never updated their billing protocols.

Prior Authorization and Parity Compliance

Mental health parity regulations under MHPAEA require that behavioural health benefits be no more restrictive than medical/surgical benefits. In practice, many commercial payers still apply more burdensome prior authorization requirements to mental health than to comparable medical services. We track payer-specific auth requirements, flag sessions approaching authorization limits, and file parity complaints when documentation supports it — protecting both your revenue and your patients' access.

Happy Billing Benchmarks for Behavioral Health:

98% Clean Claim Rate

Psychotherapy claims fail most often on timed-code mismatches, POS code errors, and missing telehealth modifiers. We catch all three before the claim reaches the payer.

Timed Code Verification on Every Claim

We cross-reference session documentation against the submitted CPT code on every psychotherapy claim — 90832, 90834, 90837, 90839/90840 (crisis), and 90847/90846 (family therapy) — before submission.

Telehealth Billing Accuracy

With telehealth representing 40%+ of behavioral health visits in many practices, billing the correct POS code and modifier combination on the first attempt is essential. We maintain a payer-specific telehealth rule matrix updated monthly.

A/R Under 35 Days

Behavioral health practices often carry high self-pay volumes and payer-specific timely filing rules. Our 24/7 team works the full payer mix — commercial, Medicaid, Medicare, and EAP contracts — continuously.

Our Specialized Process

Timed Code Audit

We verify that session documentation supports the submitted psychotherapy code — duration, modality, and clinical content — before every claim is filed. This eliminates the underpayment and overcoding risks that make behavioral health claims a frequent audit target.

E/M + Psychotherapy Capture

For psychiatrists and psychiatric NPs, we identify every session where an E/M and add-on psychotherapy code should both be billed. Capturing +90833, +90836, and +90838 on qualifying encounters routinely adds 20–30% to monthly psychiatric billing revenue.

Telehealth Compliance Review

Every telehealth claim is reviewed against our payer-specific POS and modifier matrix before submission. No more blanket application of modifier 95 to payers that require GT — or audio-only visits coded as video visits.

Authorization Lifecycle Management

We track session counts against active authorizations, file renewal requests before limits are hit, and document parity violations when a payer applies more restrictive auth requirements to behavioral health than to comparable medical services. Patients don't lose coverage mid-treatment, and your revenue stream stays unbroken.

Frequently Asked Questions

How do you handle billing for telehealth therapy sessions across state lines?

Telehealth licensure and reimbursement rules vary by state. We track the patient’s location at the time of service — not the provider’s location — for POS code selection, and we flag sessions where the provider may not hold a license in the patient’s state. Interstate Compact (PSYPACT) participation changes what’s permissible; we stay current on each state’s rules.

Can you bill for both an E/M visit and psychotherapy in the same session?

How do you manage billing for group therapy versus individual sessions?
